Project description:Human embryonic stem cells (hESC) can be differentiated into progenitors resembling trophoblast upon exposure to BMP4. Among the earliest transcription factors that are activated after the BMP4 stimulation are GATA2, GATA3, TFAP2A and TFAP2C. Using trophoblast progenitors at day 3 of BMP4-induced differentiation, here we profile the chromatin binding landscape of these 4 early transcription factors to analyse their putative targets and cross-connectivity in regualtion of trophoblast commitment.

Project description:To elucidate the molecular basis of BMP4-induced differentiation of human pluripotent stem cells (PSCs) toward progeny with trophectoderm characteristics, we produced transcriptome, epigenome H3K4me3, H3K27me3, and CpG methylation maps of trophoblast progenitors, purified using the surface marker APA. We combined them with the temporally resolved transcriptome of the preprogenitor phase and of single APA+ cells. This revealed a circuit of bivalent TFAP2A, TFAP2C, GATA2, and GATA3 transcription factors, coined collectively the “trophectoderm four” (TEtra), which are also present in human trophectoderm in vivo. At the onset of differentiation, the TEtra factors occupy multiple sites in epigenetically inactive placental genes and in OCT4. Functional manipulation of GATA3 and TFAP2A indicated that they directly couple trophoblast-specific gene induction with suppression of pluripotency. In accordance, knocking down GATA3 in primate embryos resulted in a failure to form trophectoderm. The discovery of the TEtra circuit indicates how trophectoderm commitment is regulated in human embryogenesis.

Project description:The GATA transcription factors, particularly GATA2 and GATA3 are responsible for trophoblast stem cells self renewal and differentiation in mice. However, we have a poor understanding about the contribution of GATA2 and GATA3, in the trophoblast cells in humans. Thus, the goal of this study is to define the importance of GATA factors in orchestrating global gene expression program in human trophoblast stem cells. Using a RNA interference strategy (RNAi), we depleted GATA2 or GATA3 expression in human trophoblast stem cells (GATA2 KD or GATA3 KD) . We then differentiated GATA2 KD and GATA3 KD human trophoblast stem cells into syncytiotrophoblasts(SynT) and compared global gene expression patterns via RNA sequencing (RNA-seq). Three individual experiments were performed for the differentiated SynT state. The submitted files contain the data (raw fastq files, count data and deseq2 output) from those experiments.

Project description:GATA transcription factors, particularly GATA2 and GATA3 are selectively expressed in the extraembryonic trophoblast lineage and regulates gene expression to promote trophoblast self-renewal during mammalian development. However, we have a poor understanding about the contribution of these GATA factors, in the process of syncytiotrophoblast (SynT) development. Thus, the goal of this study is to define the importance of GATA2 and GATA3 in orchestrating a global gene expression program that poises and commits mammalian trophoblast stem cells to the SynT lineage. Using the cut and run technique for GATA2 and GATA3 antibodies in the human trophoblast stem cells we are aiming to identify the direct targets of the GATA transcription factors that are essential for determining the SynT lineage. Three individual experiments were performed.

Project description:We were interested in determining what genes might be controlled by TFAP2C and/or TFAP2A, either directly or indirectly through regulation of ER-alpha and potentially other signaling pathways. We performed an microarray analysis in MCF7 cells with elimination of either TFAP2C or TFAP2A. The patterns of gene expression with alteration of TFAP2 activity were compared to changes in expression induced by estrogen exposure. Knock-down of TFAP2C in the presence of estrogen altered the pattern of several known ERalpha-regulated genes and a number of genes outside the estrogen-regulated pathways. Experiment Overall Design: 6 samples were analyzed. Experiment Overall Design: 1. MCF7 cells treated with TFAP2C siRNA, without the presence of estrogen. Experiment Overall Design: 2.MCF7 cells treated with TFAP2C siRNA, with the presence of estrogen. Experiment Overall Design: 3.MCF7 cells treated with TFAP2A siRNA, without the presence of estrogen. Experiment Overall Design: 4.MCF7 cells treated with TFAP2A siRNA, with the presence of estrogen. Experiment Overall Design: 5.MCF7 cells with no siRNA treatment, without the presence of estrogen. Experiment Overall Design: 6.MCF7 cells with no siRNA treatment, with the presence of estrogen.

Project description:We have genetically ablated the neural crest by simultaneously knocking out tfap2a and tfap2c in developing zebrafish embryos. We have collected 10 single embryos at the 15 somites stage from all nine possible genotypic combinations which can be found when heterozygous parent carriers of tfap2a and tfap2c are crossed. Embryos were prepped in singular, barcoded and RNA-Seq libraries were created using True-Seq stranded RNA-Seq LT kit. Libraries were paired end sequenced at 75bp on an Illumina Hi-Seq 2500.

Project description:The in vitro reconstitution of human germ-cell development provides a robust framework for clarifying key underlying mechanisms. Here, we explored transcription factors (TFs) that engender the germ-cell fate in their pluripotent precursors. Unexpectedly, SOX17, TFAP2C, and BLIMP1, which act under the BMP signaling and are indispensable for human primordial germ-cell-like cell (hPGCLC) specification, failed to induce hPGCLCs. In contrast, GATA3 or GATA2, immediate BMP effectors, combined with SOX17 and TFAP2C, generated hPGCLCs. GATA3/GATA2 knockouts dose-dependently impaired BMP-induced hPGCLC specification, whereas GATA3/GATA2 expression remained unaffected in SOX17, TFAP2C, or BLIMP1 knockouts. In cynomolgus monkeys, a key model for human development, GATA3, SOX17, and TFAP2C were co-expressed exclusively in early PGCs. Crucially, the TF-induced hPGCLCs acquired a hallmark of bona fide hPGCs to undergo epigenetic reprogramming and mature into oogonia/gonocytes in xenogeneic reconstituted ovaries. By uncovering a TF circuitry driving the germ line program, our study provides a paradigm for TF-based human gametogenesis.

Project description:The first lineage decisions during mouse development lead to establishment of embryonic and extraembryonic tissues. The transcription factor Cdx2 plays a central role by repressing pluripotency genes, such as Oct4 and promoting trophoblast fate at the blastocyst stage. Here we show that the transcription factor Gata3 is coexpressed with Cdx2 in the blastocyst and that overexpression of Gata3 in embryonic stem cells is sufficient to induce expression of trophoblast genes. Gata3 expression in the blastocyst does not depend on Cdx2, nor do Gata3 overexpressing cell lines require Cdx2 for expression of a subset of trophoblast genes. In the embryo, expression of Gata3, like Cdx2, depends on Tead4, and expression of both factors becomes restricted to nascent trophoblast by an Oct4-independent mechanism. These observations place Tead4 at the top of a trophoblast hierarchy, with Gata3 and Cdx2 acting downstream to induce expression of common and independent targets in this lineage. This SuperSeries is composed of the following subset Series: GSE12985: Differentiation time course of trophoblast stem cells GSE12986: Expression of Cdx2 or Gata3 in R1 mouse embryonic stem cells
